One of my students created a model of an animal cell and I would like to print it. When I try to download the STL file, Tinkercad tries to process the request. After a few minutes, I receive the 502 error messag and the download times out. When I open the model in Tinkercad, I do get a warning message about the program having a problem with the grouping of shapes. I tried grouping all the individual shapes into one model, with the thought that it might make it easier for Tinkercad to process the file, but the result was the same.
Can someone take a look at this file and see if you can download it to an STL on your end?
